What is the mission of Wtf-Domains? The registry explains: "WTF is a pop-culture term that is attractive to registrants seeking new avenues for expression on the Internet, and who are perhaps interested in demonstrations of irony, skepticism, humor, and critique. Individuals and groups will register names in .WTF when interested in editorializing, providing input, interacting with other communities, and publishing commentary. The TLD also is an acronym for various other terms and references, and could be broadly applied in several languages."

Here you can pre-register your name among the most important New Top Level Domains like the WTF-domain. Pre-registration is free, but binding.
